Composite Fire Danger Class (FDC)
Indication of the ease of suppression (or the difficulty of control) of fire burning in the predominant local fuel type, i.e. forest, scrub-land or grassland.
Forest Fire Danger Class (FFDC)
Indication of the ease of suppression (or the difficulty of control) of fire burning in the forest fuel type. For more details refer to the Fire Weather Data Tables
Grass Fire Danger Class (GFDC)
Indication of the ease of suppression (or the difficulty of control) of fire burning in the grass fuel type. For more details refer to the Fire Weather Data Tables
Scrub Fire Danger Class (SFDC)
Indication of the ease of suppression (or the difficulty of control) of fire burning in the scrub fuel type. For more details refer to the Fire Weather Data Tables
Fine Fuel Moisture Code (FFMC)
An indicator of the relevant ease of ignition and flammability of fine fuels.
Duff Moisture Code (DMC)
A rating of the average moisture content of loosely compacted organic layers of moderate depth.
Drought Code (DC)
A rating of the average moisture content of deep, compact, organic layers. This code is a useful indicator of seasonal drought effects on forest fuels and amount of smouldering in deep duff layers and large logs.
Initial Spread Index (ISI)
Combines the effect of wind speed and the Fine Fuel Moisture Code, providing a numerical rating of fire spread rate.
Buildup Index (BUI)
Combines the Duff Moisture Code and Drought Code and represents the total amount of fuel available for combustion.
Fire Weather Index (FWI)
Combines the Initial Spread Index and Buildup Index to indicate the intensity of a spreading fire (on level terrain).
